The aim of this work was to determine the mercury and methylmercury content in muscle tissue of chub (Leuciscus cephalus L.), to assess the health risks of eating the fish and to determine the number of fish meat servings that are suitable for weekly consumption. Total mercury concentrations were determined using a single-purpose atomic absorption spectrophotometer AMA 254. Methylmercury concentrations were determined by gas chromatography. The location where the highest total mercury concentrations in fish muscle tissues were found was the Vltava - Vraňany (0.236±0.1001mg/kg(-1)), and the highest methylmercury concentration was found at the Labe - Obříství (0.231±0.1056mg/kg(-1)). The conclusion based on the data ascertained is that the locations from which the lowest number of fish meat servings can be eaten are the Vltava - Vraňany and the Labe - Obříství. The results of this study helped evaluate contamination levels of rivers that flow out of the Czech Republic.
本工作旨在测定鲤鱼（Leuciscus cephalus L.）肌肉组织中的汞和甲基汞含量，评估食用鱼类的健康风险，并确定每周适合食用的鱼肉份数。总汞浓度采用专用原子吸收分光光度计 AMA 254 测定。甲基汞浓度采用气相色谱法测定。在鲤鱼肌肉组织中发现总汞浓度最高的地点是伏尔塔瓦河-弗拉尼安尼（0.236±0.1001mg/kg(-1))，而甲基汞浓度最高的地点是拉贝河-奥布里施蒂（0.231±0.1056mg/kg(-1))。根据所确定的数据得出的结论是，食用鱼肉份数最少的地点是伏尔塔瓦河-弗拉尼安尼和拉贝河-奥布里施蒂。本研究结果有助于评估流出捷克共和国的河流的污染水平。
